12.8
Control panel replacement
When replacing the whole control panel,
check compatibility of the new panel
software with the executive panel A
software. Compatibility is maintained if
the first number of software in the
control panel and in the executive
module is identical. In the example
below, the software versions are
compatible, as the first number ,,01” is
the same for both subassemblies.
Examples of software numbers:
Control panel
Executive module
01
.12.06.E1
01
.10.90.R1
The software numbers can be
read on the rating plates of the
subassemblies, or in the menu
Information.
The regulator can operate
improperly if the control panel
is
incompatible
with
the
executive module.
12.9
Executive module replacement
The requirements are the same as those
for replacement of the control panel.
12.10
Other requirements
Before using the regulator in the boiler,
verify whether the regulator meets the
boiler requirements defined in valid
regulations. Check whether the regulator
can properly and safely cooperate with
particular boiler type.
13. Connecting electrical installation
The regulator is intended to be supplied
with the following voltages:
single-phase ~230V/, 50Hz
three-phase ~400V/, 50Hz
Installation should:
include three-wire cables (with a
protective wire) for single-phase,
include five-wire cables (with a
protective wire) for three-phase,
meet the regulations in force.
Device starts to be supplied in a moment
of screwing cable cables in
HV
terminal
to
connectors
and
switching
the
installation switch to
1
(outside in a
housing cover). GZ1 silicone breaker and
CLS6 overcurrent switch in the cover
should be set to
1
. Emergency switch
should be pulled out.
